recently I discovered that I was unable to download new attachments from my email application in webos. After quite a bit of troubleshooting... I finally found that the most recent update to muffle system logging (version 22) seems to be causing a block to the file-cache. Attachments will download and then never exist in the file-cache folder. Aka they cannot be opened.
I won't pretend to know why this is an issue, but I can now confirm 100% for sure that it is.

I'll be installing an older version (v21) for now, but I felt I should report this.

Edit: You cannot simply uninstall muffle to correct the problem. Fix is a few posts down.

That s*cks, I have 6 email accounts configured, will take me ages to fix, grmbl

prolly just unlink one email and make sure the fix works for you. After the problem child is removed, I'm fairly certain you can install the old version and then unlink other accounts later. If that makes sense. Although I suppose theres no real harm in removing them all.

Any type. Upon investigation using Internalz, I found that the file-cache folders/files were never being created upon downloading of the attachment. I assume that some file permissions issue is to blame. Attachment gets downloaded -> application tries to save -> gets blocked -> reports file as downloaded, but it doesn't exist because it was never saved.

For instance ../file-cache/J/randomfile.ipk. I would browse to file-cache, but there was no folder "J" and likewise no file.

I've removed all my email accounts, removed the patch, restarted the device still getting this error

You put your accounts back in already as well? I never had problems actually downloading them. The progress bar would go fine, and then the application to open said file would start, but then error out.

Hmm weird, I sent two identical emails with attachment (.doc) to my yahoo and gmail accounts. When I actually tried it and the first time with Yahoo mail, I got a 3099 (or 3039 error - i forgot) when downloading the attachment. So I went and tried it with my gmail but the download went through. Then I went back to Yahoo mail and downloaded the attachment, this time it didn't give me errors. Everything looks fine, although I haven't tested it fully yet.
